"I think as an offense we felt like we slipped up, especially at the end of the season, the way the season ended," Vereen told SiriusXM NFL Radio on Monday (via ESPNBoston.com). "Going into OTAs, that was our focus. There is still a lot we need to work on, there are a lot of new faces, it's still a younger offense, and so we have a lot of jelling to do. But I think we're on the right track."

It will be fascinating to watch how the Patriots perform on offense in 2013. Statistically, they had one of the best units ever in 2012. This season brings questions marks: Can Danny Amendola adequately replace Wes Welker? Who will replace Brandon Lloyd? What is Rob Gronkowski's status?
